Key human-powered commands.

A display unit 2, such as a display, is provided to display data input from the outside, data resulting from information processing, and the like.

Generally, such information processing devices handle a large number of types of data. Therefore, the types of data that need to be displayed on the display section 2, for example, for data reference or data setting, will inevitably increase. In such a case,
The necessary data contents are displayed on the display section 2 by manually inputting a coded data item indicating the type of data required using combination keys on the keyboard 1.

However, in a data display device in which the data items corresponding to the data content to be displayed on the display unit 2 are specified for each data type by key combinations on the keyboard 1, the following steps are required when operating the information processing device. There was a problem.

That is, as the number of types of data to be displayed increases, the combination key operation procedure for manually inputting the data items of the required data from the keyboard 1 becomes complicated and lengthy. As a result, the time required to access the required data increases, and key operations become complicated, which increases the time required to operate the information processing device and increases the probability of making incorrect data decisions.

In order to avoid the above problem, as shown in Fig.
In addition, a plurality of display keys 4 are separately provided for inputting data items, each key corresponding to each data item. However, with such a data display device, there is a problem in that as the number of data types to be displayed increases, the number of display keys 4 must be increased.

This CPU 20 is connected to a ROM (read only memory) 22. which stores fixed data such as programs via a path line 21 consisting of a data bus, an address bus, etc. I10 interface 23 that receives data from the outside and outputs information processing results. RAM (random access memory) 2 that temporarily stores variable data such as data input from this I/○ interface 23
4. It also controls the operations of the keyboard 12, the input/output circuit 25 of the display section 11, etc. described above.

FIG. 5 conceptually shows a schematic structure of data handled in this embodiment as a data item setting means. In other words, A, B, etc. in level 1 indicate major classifications, a, b, etc. in level 2 indicate medium classifications, and furthermore, A, B, tsu... in level 3 indicate minor classifications. .

For example, for the combination (B-(j-key), 1
Data contents are set. Each index N1 of the data item corresponding to this combination. N2°N3 are 2.2.1, respectively, as shown in the figure. Each of these indexes N1
．． N2. The maximum value of N3, that is, the maximum number of classifications, is NIMAX.

It is set to N2MAX and N3MAX.

When various key signals are inputted from the keyboard 12 via the input/output circuit 25 while the display section 11 is displaying the contents of one of a plurality of data, the CPU 20 executes processing operations according to the flow chart shown in FIG. configured to run. That is, when a key signal is input, the key signal input at Pl is used to input each index (N1, N2, etc.) indicating a data item.
Skip key 14.15.1 to increase N3)
It is checked whether or not it was caused by the key operation in step 6.

If the incrementing skip key is used, then the key operation is the skip key 1 of Ll corresponding to the exponent N1.
Check whether it is 4 or not. If the L1 key is 14, the corresponding index N1 is increased. Thereafter, it is confirmed that the increased index N1 does not exceed the previously set maximum value NIMAX@, and the process proceeds to P2 as a specifying means for specifying a data item. Note that the increased index N1 is the maximum value N1M
If AX is exceeded, the value of index N1 is returned to 1 at the beginning.

At P2, the index N1 that has just been increased and the index N2 of the data item corresponding to the data content being displayed on the display section. N3
The data content corresponding to the new data item (N1.N2.N3) consisting of is retrieved, and the data content is switched and displayed on the display section 11. Thus, the processing work for this key human input signal is completed.

Note that the key signal from the skip key for increasing the index is L2.
If the key 15 or the L3 key 16 is used, the respective index N2 or
Increase N3 by 1 and proceed to P2. Then, the data contents corresponding to the data items indicated by the one index changed in P2 and the other two indexes not changed are displayed on the display section 11.

If the key signal input at Pl is not from the skip key 14, 15, 16 for exponent increase, the key signal input at P3 is the one for the exponent decrease skip key 17, 18, . '1
It is checked whether or not it was caused by the key operation in step 9. If the key operation is a decrease skip key, then the Ll'- skip key 17 corresponding to the index N1 is used.
Find out whether or not.

If the L1 key is 17, set the corresponding exponent N1 to 1.
only decreases. Thereafter, it is confirmed that the decreased index N1 has not reached O, and the process proceeds to P2.

Note that when the decreased index N1 reaches O, the value of the index N1 is returned to the aforementioned maximum value N1MAX. At P2, search for the data content corresponding to a new data item (N1°N2.N3) consisting of the now reduced index N1 and the indices N2 and N3 of the data item corresponding to the data content currently displayed on the display. , the data contents are switched and displayed on the display section 11.

Note that the key signal from the skip key for index reduction is L2.
If the key 18 or the L3 key 19 is used, the respective index N2 or
Decrease N3 by 1 and proceed to P2. 'Then, the data content corresponding to the data item indicated by the one index changed in P2 and the other two indexes not changed is displayed on the display section 11.

If the key signal is not from the skip key at P3, it is determined that the operation key 13 has been manually operated, and the processing task corresponding to the key operation is executed.

Note that three indexes N1. N2. There is no need for data contents to exist corresponding to all combinations of data items made up of N3. If the data content does not exist, the data item can be skipped (sequentially forwarded).

With the data display device configured in this way, simply by pressing each of the skip keys 14 to 19, the data content displayed on the display unit 11 can be sequentially changed in response to changes in the exponent of the pressed skip key. Change.

Then, the data content of the required data type is represented in representation part 1.
